Phase 2 Lowland Grassland Vegetation
The purpose of this data capture was to characterise the semi-natural lowland grassland vegetation of Wales and to provide a systematic conservation assessment of the sites surveyed. This is a GIS dataset containing vegetation types recorded during the Phase 2 Lowland Grassland survey of Wales (1987 - 2004). A detailed survey of plant communities in semi-natural lowland grassland vegetation. Sites vary in size and complexity from small uniform hay-meadows of less than 1 ha to extensive wet-dry pasture systems covering over 100 ha. The survey was started by Nature Conservancy Council (NCC) and continued since 1991 by Countryside Council for Wales (CCW).

Surveyed all forms of semi-natural neutral, acidic and calcareous grassland in lowland Wales, as well as wetter Molinia (purple-moor grass) and Juncus (rush) pasture communities and associated soligenous mires. Community definition follows the National Vegetation Classification (NVC). At each site, homogeneous stands of vegetation were identified, sampled with 2 x 2 m quadrats and mapped onto Ordnance Survey base maps or aerial photographs at 1:5000 scale. The main limitation of the data is their age. Habitat composition may change over time due to successional trends and also through agricultural treatments or even planned developments. A record of a vegetation type in the data is therefore no guarantee that it is still extant on the ground.
